Area code 218 is part of the North American Numbering Plan (NANP) of the public switched telephone network for the northern part of the US state of Minnesota. It is one of Minnesota's original two codes, although its geographical area has been modified since inception. By area, the region is the largest area code in Minnesota, covering roughly the northern half of the state. It includes the cities of Duluth, Hibbing, Brainerd, Bemidji, Fergus Falls, and Moorhead.
Area code 320 is the telephone numbering plan code covering most of central Minnesota. It was the fourth Minnesota area code, and the first new one in the state in 42 years. It was created in 1996 by carving out of the western part of area code 612, which originally stretched border-to-border from Wisconsin through the Twin Cities to South Dakota. The Twin Cities region retained 612, with St. Cloud, Alexandria, and Willmar switching to 320.
More recently, the 612 area shrank to include only Minneapolis and a few inner suburbs. 320 now borders every Minnesota area code except 612. Area code 651 split from 612 in 1998. The 651 area borders Wisconsin, while area codes 763 and 952 were split from 612 in 2000. Area code 218 borders 320 to the north, and area code 507 covers southern Minnesota.
Area code 507 is the telephone numbering plan code for the southern fifth of Minnesota, including cities such as Rochester, Mankato, Worthington, Fairmont, Albert Lea, and Austin. It was the third area code created for use in the state in 1954, following the original 218 and 612. It was created from the southwestern portion of 218 and the southern portion of 612.
In the original 1947 plan, area codes containing "0" (zero) as a middle digit were only assigned to states that were entirely covered by a single area code. Area code 507, along with area code 606 in Kentucky and area code 607 in New York, were the first area codes with a middle digit of "0" to be assigned to states that were covered by more than one area code.
The region was directly bordered by 612 (to the north) until that area code was divided in the 1990s. The western half of 507 bordered area code 320 starting in 1996, and then later came to border also area code 651 (1998) and area code 952 (2000). The northern border of 507 was modified slightly so that expanding communities in and near the Twin Cities would be more closely linked with that region by telephone. 612 has now shrunk down to include just Minneapolis and a few surrounding suburbs, and no longer borders 507.
